ln Vitro |
Distinct from DPP-IV, NEP is extensively present in endothelial cells, vascular smooth muscle cells, cardiac cells, and renal epithelial cells. It cleaves GLP-1(7-36)amide or GLP-1(9-36)amide to produce GLP-1(28-36)amide[1]. Hepatocytes treated with GLP-1(28-36)amide (100 nM) for 24 hours show a direct modulation of mitochondrial oxidative metabolism, including gluconeogenesis[1]. Human hepatocytes have a longer plasma half-life (t1/2 = 24 min) for GLP-1(28–36)amide than mouse hepatocytes (t1/2 = 13 min)[1].

ln Vivo |
When GLP-1(28-36)amide is given to diet-induced obese mice for nine weeks at a rate of 18.5 nmol/kg BW/day, the development of hepatic steatosis is inhibited[1]. In a diabetic mouse model with β-cell damage, an intraperitoneal injection of 18 nmol/kg GLP-1(28-36)amide once daily for nine weeks demonstrated cytoprotective action on pancreatic β cells by increasing mass and boosting proliferation[1]. A six-week injection of 18.5 nmol/kg GLP-1(28-36)amide enhanced the disposal of glucose from the liver in mice fed a high-fat diet, according to an in vivo study[1]. This improvement is linked to elevated cAMP levels and phosphorylation of the PKA target. Male C57BL6/J mice (10–12 weeks old) were given GLP-1(28) -36)amide for 20 minutes. After that, the isolated hearts experienced global ischemia for 30 minutes and reperfusion for 40 minutes. The recovery of left ventricular developed pressure (LVDP) was significantly higher in the GLP-1(28–36)amide group than in the vehicle-treated hearts[1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (2.30 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (2.30 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
